2004 Mazda RX-8 Service Highlights (3378–1U–03C)
P0103 MAF sensor circuit high input
•
The PCM monitors the input voltage from the MAF sensor when the engine is running. If the input voltage is
more than 5.0 V, the PCM determines that the MAF sensor circuit input voltage is high.
P0107 BARO sensor circuit low input
•
The PCM monitors the input voltage from the BARO sensor when the engine is running. If the input voltage is
less than 0.2 V, the PCM determines that the BARO sensor circuit input voltage is low.
P0108 BARO sensor circuit high input
•
The PCM monitors the input voltage from the BARO sensor when the engine is running. If the input voltage is
more than 4.8 V, the PCM determines that the BARO sensor circuit input voltage is high.
P0111 IAT sensor circuit range/performance problem
•
The PCM compares the IAT with the ECT when the engine is running. If the IAT is higher than the ECT by 40
°
C
{104
°
F}, the PCM determines that there is an IAT sensor circuit range/performance problem.
P0112 IAT sensor circuit low input
•
The PCM monitors the input voltage from the IAT sensor when the engine is running. If the input voltage is less
than 0.1 V, the PCM determines that the IAT sensor circuit input voltage is low.
P0113 IAT sensor circuit high input
•
The PCM monitors the input voltage from the IAT sensor when the engine is running. If the input voltage is
more than 4.8 V, the PCM determines that the IAT sensor circuit input voltage is high.
P0117 ECT sensor circuit low input
•
The PCM monitors the input voltage from the ECT sensor when the engine is running. If the input voltage is
less than 0.2 V, the PCM determines that the ECT sensor circuit input voltage is low.
P0118 ECT sensor circuit high input
•
The PCM monitors the input voltage from the ECT sensor when the engine is running. If the input voltage is
more than 4.8 V, the PCM determines that the ECT sensor circuit input voltage is high.
P0122 TP sensor No.1 circuit low input
•
The PCM monitors the input voltage from the TP sensor No.1 when the engine is running. If the input voltage is
less than 0.3 V, the PCM determines that the TP sensor No.1 circuit input voltage is low.
P0123 TP sensor No.1 circuit high input
•
The PCM monitors the input voltage from the TP sensor No.1 when the engine is running. If the input voltage is
more than 4.8 V, the PCM determines that the TP sensor No.1 circuit input voltage is high.
P0125 Insufficient coolant temperature for closed loop fuel control
•
The PCM monitors the ECT after cold engine start. If the ECT does not reach the specification in a certain
period, the PCM determines that the coolant temperature for closed loop fuel control is insufficient.
P0126 Insufficient coolant temperature for stable operation
•
The PCM monitors the ECT after the engine start for a certain period. If the the ECT never exceeds 71
°
C {160
°
F} when the following conditions are met, the PCM determines that the coolant thermostat is stuck open.
MONITORING CONDITIONS
—
Soak time: more than 6 hour
—
IAT: more than –10
°
C {14
°
F}
—
Vehicle speed: more than 10 km/h {6.2 mph}
—
LOAD: more than 21.9 %
P0128 Coolant thermostat problem
•
The PCM calculates the radiator heat radiation ratio while the following conditions are met. If the calculated
value exceeds the threshold, the PCM determines that the coolant thermostat is stuck open.
MONITORING CONDITIONS
—
Soak time: more than 6 hour
—
IAT: more than –10
°
C {14
°
F}
—
ECT at engine start: less than 35
°
C {95
°
F}
—
Vehicle speed: more than 40 km/h {24.9 mph}
P0130 Front HO2S circuit problem
•
The PCM monitors the front HO2S impedance when under the front HO2S heater control. If the impedance is
more than 500 ohms, the PCM determines that there is a front HO2S circuit problem.
P0131 Front HO2S circuit low voltage
•
The PCM monitors the input voltage from the front HO2S and the front HO2S output current when the engine is
running. If the input voltage is less than 1.8 V or the output current is less than -5 mA, the PCM determines that
the front HO2S circuit voltage is low.
P0132 Front HO2S circuit high voltage
•
The PCM monitors the input voltage from the front HO2S and the front HO2S output current when the engine is
running. If the input voltage is more than 3.8 V or the output current is more than 5 mA, the PCM determines
that the front HO2S circuit voltage is high.
P0133 Front HO2S circuit slow response
•
The PCM monitors the front HO2S output current and short term fuel trim (SHRTFT) when the following
conditions are met. If the output current response is lower than that expected from the fuel trim, the PCM
determines that the front HO2S circuit response is slow.
